What if I told you that right here lies a key to Hong Kong’s sustainable future? This is the San Wai Sewage Treatment Plant. It stands as a testament to the city’s commitment to managing its waste and protecting its environment.
The San Wai Sewage Treatment Plant plays a vital role. It treats wastewater from the Northwest New Territories. This helps to meet the needs of a growing population in the Yuen Long area.
Let’s dive into some numbers. The San Wai Sewage Treatment Plant has a maximum peak capacity close to 500000 cubic metres per day. It used to have a daily capacity of 164000 cubic metres. The plant’s expansion significantly increases its ability to handle wastewater.
SUEZ has been instrumental in upgrading the San Wai Sewage Treatment Plant. They partnered with ATAL and China Harbour. Together they secured a contract to design, build and operate the extension of the plant. The contract is worth 353 million euro. SUEZ’s share is approximately 99 million euro.
The upgrade includes innovative technology. Chemically enhanced pre-treatment with Densadeg will be added. This is followed by ultraviolet disinfection. This process improves the wastewater treatment performance.
The Drainage Services Department awarded the contract. This upgrade helps to enhance water treatment facilities for Hong Kong’s expanding urban population. It also tackles the issue of limited land.
The San Wai Sewage Treatment Plant project commenced in May 2016. It aimed to improve effluent quality. It also aimed to handle increased sewage flow. This is to cope with the increasing demand for sewage treatment in the North West New Territories. The plant has a capacity of 200000 cubic metres per day. It provides chemically enhanced primary treatment and disinfection. The San Wai Sewage Treatment Plant has been commissioned since 2020 or 2021.
The Administration Building cum Workshop has achieved BEAM Plus Final Platinum accreditation. This is a testament to its green features. These features include landscape design with native species. It also uses pervious materials to reduce surface runoff.
The plant uses sustainable forest products. It also uses regional materials extracted and manufactured within 800km of the site. Energy-efficient air-conditioning and optimized lighting design are used. Renewable energy contributes to at least 2.5% of total energy consumption.
Twin water tanks serve potable and flushing water systems. The plant has IAQ Excellent Class. It also features fresh air provision and increased ventilation.
The San Wai Sewage Treatment Plant is more than just a treatment facility. It shows Hong Kong’s dedication to sustainability and environmental protection. Its innovative technologies and green features set a high standard for waste management.
